7 This invention relates to new and useful improvements in a window construction and method for inserting sash cords or chains therein.

An important object of this invention is to provide improved means for coupling a'sash cord or chain to a window sash while the window sash is slidably mounted in its window frame or casing, without the necessity'of removing the sash from the Window frame or casing.

The invention has for an object to provide a removable section in the side arms of a window frame arranged at a location so that the cus tomary counterweights working within the win dow frame are accessible, particularly afterthe 135'; sash cordor chain has been broken. Heretofore,

in order to repair a sash cord or chain it was required that the window guide strips of the window frame be removed and that certain other strips of the frame be removed before the sash 'weights wereaccessible. It required an experienced person to make 'such repairs. With the invention a sash cord or chain may be replaced in five minutes. or less, without requiring any skill on the part of the person doing the job. The'invention may be installed in old window frames as well as in new ones. Because the invention involves no complicated mechanism or construction there will be no increase in cost for its application to a window during the manu- 1 facture thereof.

The'invention has for an object the teaching of a method of repairing the sash cords by which an experienced person may make a repair in a fraction of the time required to make a similar repair with present day methods, and by which an inexperienced person could "easily make the repair. I

For further comprehension of the" invention, and of the objects andadvantages thereof, reference will be had to the following description and accompanying drawing, "and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 8 is a perspective view of a cord or chain clamp necessary in carrying out the method.

. Fig. 9 is a perspective view of a mouse used in carrying out the method.

The window construction, according to this invention, is characterized by a sash frame having a side arm ID with strips ll thereon forming grooves H for one of the sides of the inner and outer sashes l3 and M on the frame. For each sash there is a conventional. pulley l5 mounted upon the top portion of the side arm over which the sash support cord or chain 16 extends. At their inner ends each cord or chain [6 has a counterweight I! attached to it. At their outer ends each cord or chain I6 is attached to the side of the sash in the following manner:. There is an L-shaped bracket I8 having one arm I8a extended within a groove formed in the top of the window sash, and a vertical arm l8b extended downwards in the groove formed in the side of the window sash. Preferably, these arms are made of half oval material so that they may fit into correspondingly formed grooves and be rigidly supported.

The lower end of the arm l8b is formed with an oval or bayonet opening IS. The loop of relatively stiff and strong wire 20 has its ends adjacent each other and formed into hook portions 2|. These hook portions are engaged through the opening IS. The end of the sash cord or chain I6 is engaged through the loop 20 and the hook portions 2| are engaged through the open- I ing I9 in a manner so that the hook portions 2| first engage into the large portion of the opening l9. This opening l9 has the smaller portion at the top so that when the loop of wire 20 is turned around to the' vertical position, as shown in Figs. 4, 5 and 6, the sides of the loop will be forced together and tightly grip and hold the end portion of the sash cord or chain. The dot and dash lines 20 in Fig. 6 indicate the position of the loop 20 when its hook portions 2| are first engaged into the opening l9.

A section of the side arm 'ID and one of the strips l l at the bottom or near the bottom of the side arm of the sash frame is separate and re an opening through the side arm so that the sash weight within the frame may be reached. The upper and lower end portions of the removable section 24 is constructed in a manner that tends to maintain its position on the sash frame. Specifically, the strip portion lid of the removable section 24 has a top beveled edge III) which engages a complementary bevel at the end of the adjacent portion of the strip l l.

The removable section of the side arm is formed with a recessed portion 2a engaging a corresponding recessed portion in the side arm I0. Similarly, at the bottom the removable section 24 is formed with a recessed portion 24b engageable with a corresponding portion of the side arm. The lower end of the strip portion [la is cut at right angles so as to rest upon the adjacent end portion of the continuation of the strip portion I. A screw 25 engages through the strip portion Ila and into the material of the side arm H] to hold the removable section fixedly in position. The bracket I8 is held on the window sash by screws 28 engaging through the top arm and into the material of the sash.

In Fig. 7 a wedge is illustrated which comprises a strip of material 28 having an offset end portion 28a at one end and a ring portion 28b at the other end. This wedge may be utilized to hold a window sash in raised position by forcing the offset end 2811 between the adjacent edges of the window sash and the window frame.

In Fig. 8 a clamp is shown consisting of a piece of wire 29 having a gripping loop portion 29a at one end and. a ring portion 2917 at the other end. The loop portion 290. has a flared end 2$aa to facilitate its engagement upon a sash cord or chain. I

In Fig. 9 a mouse is illustrated comprising a looped string 3!! on one end of which there is a plurality of small weights 3|.

The method of replacing a sash cord, in accordance with this invention is as follows: The mouse 39 is first attached to a string and dropped over the pulley l5 and let down within the counterweight portion of the window frame. The window sash is then lifted to its raised position and held in this position by engaging the wedge 28 between the adjacent edges of sash and the window frame. The removable section 24 of the window frame is then removed. A chain or cord is attached to the mouse, and the wedge which holds the window sash is removed so that the window sash may be lowered.

It is possible to pull the chain or cord over the pulley [5. The inner end of the chain or cord is then attached to the counterweight I! through the opening in the window frame which was produced when the section 24 was removed. After the counterweight has been attached, the cord or chain is pulled outwards so that the counterweight is lifted to a position substantially near the pulley I 5. The clamp 29 is then engaged on the window cord or chain immediately adjacent the pulley I5 and holds the cord in position. The outer end of the cord is therefore free and loose and is not being drawn by the counterweight and may be conveniently attached to the window sash. The bracket i8 is first removed from the window sash by screwing out the screws 26. Then the outer. end of the chain or cord is engaged by the anchorage piece of wire 20. This is possible by first turning the anchorage wire through the-n engaging the sash cord or chain through the loop, and then turning the anchorage wire back to its gripping position.

After the outer end of the sash cord or chain has been attached to the bracket 18 as specified, the bracket is replaced upon the sash and secured in position by re-engaging the screws 26. Then the clamp 29 is removed from the sash cord or chain and the window is raised. Finally, the removable section 24 is replaced and secured in position by the screw 25. The job has thus been completed without the necessity of dis-assembling strip portions of the window frame.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
